Ordered 8 of them to take the dog for a walk in the summer. 4 were badly sewn and fell apart. 2 were substitutes for bad shirts that were bad in themselves. They're a bit breathable, but also see-through, which is why I'm concerned about the UPF rating. Also, there is no indication on the packaging that they are UPF rated and as I am undergoing melanoma chemo which puts me at additional risk of new skin cancer this is not bothersome. They are big and don't shrink.
